Multilyser V3 – Overview

The Multilyser is a combination of the s::can Nitrolyser and Carbolyser probes. The Multilyser measures organic carbon & nitrates for a multitude of pre-defined applications. The Multilyser is suitable to be used for surface water, groundwater, drinking water as well as wastewater applications. This accurate, easy to use probe optimises performance and cost-effectiveness.

The Multilyser monitors 4 of the following parameters: Turbidity, TSS, TS, BOD, COD, TOC, DOC, COD f, NO3-N, NO-3, UV254, and UV254 f.
